Abstract (en)
A wireless communication system includes a mobile terminal (3), a base station apparatus (4), a data relay apparatus (1) and a server apparatus (5). One of them includes a transmitting unit (13), a monitoring unit (11) and a determining unit (12). The transmitting unit (13) transmits a transmission data and receives an acknowledgement data (ACK) corresponding to the transmission data through a communication line (101+102). The monitoring unit (11) monitors the transmission data and the acknowledgement data (ACK). The determining unit (12) determines a retransmission timeout period (new RTO) based on a monitored result (Dsize, RTT) in a certain period. The transmitting unit (13) retransmits the transmission data when the acknowledgement data (ACK) is not received in the retransmission timeout period (RTO).
